Sujee Maniyam commented on HBASE-4440:
--------------------------------------
so you are proposing that
1) whether we use presplit option or not, table has to be recreated for all
write-mode tests.
This changes the behavior for all write-tests. Currently table is only
created if it doesn't exist.
2) or pre-split should try to split the table without re-creating it.
> add an option to presplit table to PerformanceEvaluation

> PerformanceEvaluation a quick way to 'benchmark' a HBase cluster. The
> current 'write*' operations do not pre-split the table. Pre splitting the
> table will really boost the insert performance.
> It would be nice to have an option to enable pre-splitting table before the
> inserts begin.
> it would look something like:
> (a) hbase ...PerformanceEvaluation --presplit=10 <other options>
> (b) hbase ...PerformanceEvaluation --presplit <other options>
> (b) will try to presplit the table on some default value (say number of
> region servers)
